Wisdoms tooth extraction, can I drink alcohol 2 days later?

Not recommended. If no complications, you should have a stable clot after 24-48 hours following extractions, so after 3-4 days you can consume alcohol in moderation.
Why? Let's say you had a small operation on your arm and had a slightly open wound there. Lets say the operation was done two days ago. Would you pour a scotch or bourbon over the wound and think it would have no affect?
